Ectopic liver tissue in the esophagus: A case report

INTRODUCTION: Ectopic liver (EL) is a rare entity, which is reported to develop at various sites, such as the abdominal cavity, the retroperitoneal cavity, the pleural cavity, and the mediastinum. PATIENT CONCERNS: A 27-year-old previously healthy Chinese man suffered from a discontinuous abdominal pain in the upper abdomen for 2 months. DIAGNOSIS: The upper gastrointestinal endoscopy revealed there was a polypoid mucosal uplift on the distal region of the esophagus near the cardia. INTERVENTIONS: Endoscopic polypectomy was performed. OUTCOMES: Pathology examination showed the liver tissue. CONCLUSION: EL should be excised as it may possibly lead to the development of a malignancy. Endoscopic resection was found to be safe and reliable in this case.
